Introduction

# The topic of our project is "Analysis and Prediction of Factors influencing Nuclear Power Plant Cost."

# The main time consuming task for our project was Data Sourcing and Data Cleansing our our csv file. Around 80-90% of the effort went into collating the final csv file.

# The goal of our project is to know what factors influence the cost of a nuclear power plant.

# In our Project, the response variable (dependent variable) shall be "Cost (US$)" (In Billions).

# The Predictor variables (independent variables which influence the varaible "Cost") shall be the following: -

# 1) Country: - Qualitative variable which lists the name of the country where the nuclear reactor was made. 21 types of countries are listed in our csv file.

# 2) Reactor Type: - Nuclear energy can be implemented in many different ways; hence the different types of Nuclear Reactors. In our data set, we have a list of 7 different reactor types.

# 3) Gross Capacity (MWe): - The amount of electricity the nuclear reactor can generate during its operation. The units are in Mega Watts Electric.

# 4) Thermal Capacity (MWt): - The amount of heat the nuclear reactor generates due to fission. Do note that heat is converted to electricity. The units are in Mega Watts Thermal.

# 5) Efficiency Percentage: - How efficient is the nuclear reactor in converting heat to electricity? The more the efficiency; the more heat is converted to electricity.

# 6) Starting Year: - The year when the construction of that nuclear reactor started.

# 7) Duration (in years): - The number of years it took to make that nuclear reactor from start to end.

# 8) Average Inflation Percentage: - The amount of inflation that occurred (YoY) during the time period it took for construction of the reactor. 

# 9) Average Concrete Price: - The average concrete price during the time period it took for construction of the reactor. (Producer Price Index (PPI) value is given)

# 10) Average Steel Price: - The average steel price during the time period it took for construction of the reactor. (Producer Price Index (PPI) value is given)

Hypothesis

# Our Hypothesis of how the predictor variables should affect the response variable are as follows: -

# 1) Country: - We expect to see different prices of nuclear reactors on the basis of different countries due to various differences in labour costs, laws and regulations, financing methods which are paticular for that specific country etc.

# 2) Reactor Type: - We expect to see that the reactor type "PWR" be the cheapest reactor to be constructed because it is the most common type of nuclear reactor to be made. Economies of scale dictates that enterprises obtain due to their scale of operation more cost advantages over others who cannot scale.

# On a similar note, we expect to see "FBR" reactor to be the most costly one becuase it is one of the most challenging reactor to be made.

# 3) Gross Capacity (MWe): - The more electricity a nuclear reactor generates, the more costly the reactors should be, since the conventional island would be bigger in size.

# 4) Thermal Capacity (MWt): - The more heat a reactor generates, the more costly that reactor should be, since the reactor core would be bigger in size.

# 5) Efficiency Percentage: - The more efficient the reactor is, it means the more expensive turbine and generator in the conventional island was used. Hence more the efficiency, more the cost.

# 6) Starting Year: - We expect to see the reactors which were made in earlier years to be cheaper than the reactors which are made in modern times due to less safety regulations, lax laws and ease of financing during earlier times.

# 7) Duration: - The more time a reactor takes to be constructed, the more costly it should be due to cost overruns etc.

# 8) Average Inflation Percentage: - The more the inflation is during a certain period of time, the costlier the things would be. 

# 9) Average Concrete Price: - Over 95% of materials which makes a nuclear reactor is steel and concrete. We expect to see, the more the average price of steel, the more the reactor cost.

# 10) Average Steel Price: - Over 95% of materials which makes a nuclear reactor is steel and concrete. We expect to see, the more the average price of steel, the more the reactor cost.

Global F-Test

#We ask the global question, Is this multiple regression model any good at all?? The answer is that we can test some hypotheses to see the relationship between the response and predictors. The first of these hypotheses is an overall F-test or a global F test which tells us if the multiple regression model is useful. To address the overall question, we will test

# H0 : β1=β2=...=β7=0
# Ha : At least one βi is not zero (i=1,2,...,7)

# Our null hypothesis basically means that all of our supposedly Independent variables are junk food and not useful at all.

# Our Alternative Hypothesis means that at least one of the independent variable is useful in our model.

# We therefore shall now do ANOVA testing.

# 4 sub-models can be formed from the above equation. It depends upon the value of Country and Reactor_Type predictor variable; which sub model shall be used in the end.

# Country can have either Iran, China or USA value.

# Reactor_Type can have either value of HTGR or not.


# Defining and interpreting each sub model: -






# 1) Country = Every country except for Iran, China and USA, Reactor_Type = Can be any reactor type: -

# Cost_Billion_Dollars = -2.0353231  + 0.0013776*Gross_Capacity_MWe -0.0085935*Duration + 0.0214370*Average_Concrete_Price.


# Interpretation : - 

# 1) For every increase in Gross_Capacity_MWe by 1 MWe, there is an increase of 0.0013776 Billion $ of the reactor cost; keeping all other variables constant.

# 2) For every 1 year increase in the Duration, there is an decrease of 0.0085935 Billion $ of the reactor cost; keeping all other variables constant.

# 3) For every increase in Average_Concrete_Price by 1 unit, there is an increase of 0.0214370 Billion $ of the reactor cost; keeping all other variables constant.







# 2) Country = IRAN, Reactor_Type = Can be any reactor type: -

# Cost_Billion_Dollars = -2.0353231 + 9.5331245*Country(IRAN) + 0.0013776*Gross_Capacity_MWe -0.0085935*Duration + 0.0214370*Average_Concrete_Price


# Interpretation : - 

# 1) For every increase in Gross_Capacity_MWe by 1 MWe, there is an increase of 0.0013776 Billion $ of the reactor cost; keeping all other variables constant.


# 2) For every 1 year increase in the Duration, there is an decrease of 0.0085935 Billion $ of the reactor cost; keeping all other variables constant.

# 3) For every increase in Average_Concrete_Price by 1 unit, there is an increase of 0.0214370 Billion $ of the reactor cost; keeping all other variables constant.

# 4) Whenever a nuclear reactor is made in IRAN, the reactor cost 9.5331245 Billion $ more.






# 3) Country = USA, Reactor_Type = Can be any reactor type: -

# Cost_Billion_Dollars = -2.0353231 + 0.0013776*Gross_Capacity_MWe -0.0085935*Duration + (0.0214370 + 0.0436586*Country(USA))*Average_Concrete_Price.

# Since Country(USA) == TRUE, Therefore value of Country(USA) = 1. Hence: -

# Cost_Billion_Dollars = -2.0353231 + 0.0013776*Gross_Capacity_MWe -0.0085935*Duration + 0.0650956*Average_Concrete_Price.

# Interpretation : - 

# 1) For every increase in Gross_Capacity_MWe by 1 MWe, there is an increase of 0.0013776 Billion $ of the reactor cost; keeping all other variables constant.


# 2) For every 1 year increase in the Duration, there is an decrease of 0.0085935 Billion $ of the reactor cost; keeping all other variables constant.

# 3) For every increase in Average_Concrete_Price by 1 unit, there is an increase of 0.0650956 Billion $ of the reactor cost; keeping all other variables constant.

# Interpretation : - 

# 1) For every increase in Gross_Capacity_MWe by 1 MWe, there is an increase of 0.0013776 Billion $ of the reactor cost; keeping all other variables constant.


# 2) For every 1 year increase in the Duration, there is an decrease of 0.0085935 Billion $ of the reactor cost; keeping all other variables constant.

# 3) For every increase in Average_Concrete_Price by 1 unit, there is an increase of 0.0214370 Billion $ of the reactor cost; keeping all other variables constant.

# 4) When CHINA is making a nuclear reactor of type HTGR, then it costs them 14.1141829 Billion dollars more to construct that reactor.

Higher Order Model

# We shall now try to make a higher order model by keeping our interaction model as our foundation.

# We shall now use GGPairs for our higher order model.

# GGPairs is used only after making your basement. i.e. reduced model.


# We shall now check all pairwise combinations of predictors and look at the correlation between them using GGPairs().
